The class file stores bytecode and related metadata in a strict binary format. Understanding them can help debug, understand language features, develop tools, and improve security awareness.

PHP Master | Monitoring File Integrity
Article Introduction：Key Points
Monitoring file integrity is essential for website management and it helps detect when files are added, modified, deleted, or corrupted accidentally or maliciously. Hashing the contents of a file is a reliable way to monitor such changes.
The hash_file() function of PHP can be used to create file structure configuration files for monitoring. The hash value of each file can be stored for later comparisons to detect any changes.
